I have figured out why I cannot mount my JFS from my external drive under Linux. Under OS/2 I grew my JFS to span two partitions when I needed more room. But Linux doesn’t like this.
There is some indications that evms supports this, but I haven’t been able to make it work.
My main goal is to backup my laptop data to the external drive. I realized that I still have forty-something GB of free space on my external drive. So I could format that and use that as backup space.
Now I cannot access my JFS partition from OS/2. Ugh. I hope tomorrow I can use OS/2’s fdisk/LVM to fix everything up, and use it to create another JFS partition to backup my laptop to; if I’m lucky.
Do you know that feeling you get when you have been mucking around with partitions, and now you cannot access your data?
